Dear Friends I've here one ATM's Hi-speed Relays. I think its function was a telephonic function. Or was it used to another matters? RF included? Do you know its released year? +/- Thank you for your time Best Regards Mário Coelho

Hi Mario, Could You please sketch the connections of the device? As a first approach I assume either a kind of "microphone amplifier" or a Telegraphic relay having no (or rather no) contact bouncing. This is necessary to restore wire telegraphy signals in particular in high speed (machine) morse or in early telecopy. In Germany such relays bore the name "Telegraphenrelais" and had a response time (bouncing included) of max. 2 milliseconds. They were mainly used in Teletype circuits and systems. (But that was considerably later than Your device.) regards Kobi |

Hi, Thank you for your reply. Schematic is very simple. I only didn't draw one regulator "Marking spacer" that is visible (at right) in last pictures. Best Regards Mário

I think it is a polarised telegraphic relais. regards KoBi |

Thank You again. However this relais (for telegraphic use) may not be an interesting subject to Rmorg. Do You agree? Cordially Mário |

Put it in, since the manufacturer is already there, why not. It would find company by a crystal set of mine... |

Dear Mr. Konrad It was uploaded. I hope Your cristal set doesn't mind to keep company with one which has so limited performances. (flip and flop) :-) Cordially Mário |
